@alexmack You are correct. HomeKit will require specific hardware components that are not in our current hardware. When HomeKit was first announced last year we weren’t sure as to how the integration would take place. But, we have learned what you have learned and it will indeed require an update to our hardware. We don’t yet have plans to explore this with the current hardware.
Hope that helps, let us know if you have any other questions. Thanks and have a great day!
